ISO/IEC 14763-4:2021/Cor 1:2022

Overview

ISO/IEC 14763-4:2021/Cor 1:2022 is a technical corrigendum to the international standard for the implementation and operation of customer premises cabling, Part 4: measurement of end-to-end (E2E) links, modular plug terminated links (MPTLs) and direct attach cabling. The corrigendum clarifies transmission-limit testing guidance by explicitly linking E2E testing to recognized connector specifications and expands the normative bibliography with additional connector standards.

Key topics and technical points

• Scope: Measurement and verification practices for installed cabling topologies where cabling is terminated at both ends (E2E links), MPTLs and direct attach cabling.
• Corrigendum change: The corrected text specifies that E2E link testing should be used to provide assurance of installed cabling terminated at both ends in accordance with these connector standards:
  • IEC 60603-7 series
  • IEC 61076-3-106
  • IEC 61076-3-117
  • IEC 61076-2-101
  • IEC 61076-2
  • IEC 61076-2-109
  • IEC 61076-3-104
  • IEC 61076-3-110
• Bibliography update: Adds IEC 61076-2 (circular connector sectional specification) and IEC 61076-3-110 (detail specification for free and fixed connectors for data transmission up to 3 000 MHz), ensuring the standard’s references cover modern connector types used in high-frequency cabling.
• Focus areas: Conformance testing of E2E links and MPTLs to transmission limits, appropriate test practices for direct attach cabling, and alignment of measurement criteria with connector product specifications.

Practical applications

• Cabling installers and certifiers use this standard to validate that installed copper and certain direct-attach link assemblies meet required transmission performance when terminated with the referenced connectors.
• Network designers and engineers rely on the guidance to select connector types and link configurations that will be verifiable by standardized E2E test methods.
• Facilities and IT managers apply the standard for acceptance testing, warranty verification and troubleshooting of structured cabling systems.
• Test equipment vendors reference the corrected guidance when implementing test limits and reporting formats for E2E and MPTL certification tools.

Related standards

• IEC 60603-7 series (modular connectors)
• IEC 61076 series (connectors for electronic equipment), including the newly referenced:
  • IEC 61076-2 – Sectional specification for circular connectors
  • IEC 61076-3-110 – Detail specification for free and fixed connectors up to 3 000 MHz

This corrigendum improves clarity for practitioners who perform cabling certification and helps ensure measurement practices are consistent with current connector product specifications.
